+qemu-system-riscv32: Some ROM regions are overlapping
+These ROM regions might have been loaded by direct user request or by default.
+They could be BIOS/firmware images, a guest kernel, initrd or some other file loaded into guest memory.
+Check whether you intended to load all this guest code, and whether it has been built to load to the correct addresses.
+
+The following two regions overlap (in the memory address space):
+  output/images/fw_jump.elf ELF program header segment 1 (addresses 0x0000000000000000 - 0x00000000000278cc)
+  mrom.reset (addresses 0x0000000000001000 - 0x0000000000001028)
